B-complex and moodiness

I have been taking a high potency b-complex 1 time a day and I have noticed I have been really irritable afterwards. Any thoughts?

Here is my experience with B-complex. I kept reading that it's good to take, and that B vitamins are water solluble so the body just gets rid of the excess, etc. , so I tried it. I took the B-50 complex. Here is what happened:

The first thing I noticed after only a couple of days, was that my hair took on a dull look - lost all its shine. Then I became very, very depressed. I also started bruising a lot easier. I was also hungry all the time, terrible food cravings. The depression worsened over a period of a week or two, until I finally said to myself, "What did I add recently?" I remembered the B-complex, and looked up dangers of B supplements. Sure enough, I read that the body can't process large amounts of certain B vitamins without having to pull all kinds of micronutrients out of your body to do it, so you end up deficient. I stopped the B-complex, and within a few days my hair is shiny and beautiful, and I am no longer depressed. Food cravings are gone.

I had given it to my 20 yr. old daughter as well, and she reported after a week or so that her arms got suddenly weak and she almost dropped her violin during orchestra practice. Then I read that excessive B vitamins will attach to your nerves and cause limb weakness. She also started bruising a lot. Needless to say she's off it too now.

Eating whole foods is the best medicine!

Yes when I take a certain brand high-potency vitamin B Complex I feel a lift in mood but next day big drop to point of depression. I don't remember having this problem on a different brand (probably lower potency too like B50). I would like to know too why because B vitmains are important and may be hard to get just from diet alone.

Hello Lima,

Re Vitamin B complex intake/ your reaction.

Well, your report is vexing. The brand you take gives you a "lift" and the next day you drop into a depression. I have been taking various B complex brands for many years and never experienced ... or heard of ... what you describe. I'm now taking a liquid form of vitamins and minerals (twice daily after morning and afternoon or early evening meals) and am of the opinion that the liquid form (pungent)... is better absorbed. Also I've started taking digestive enzymes after EVERY meal.

This intake of enzymes was the result of me taking a "blood analysis test" (google " you tube microscopy blood analysis") and you'll find some youtube illustrations of how your red blood cells are functioning and what other issues are at work on the cellular level (fungus, white blood cell health, plaque level)...all quite fascinating and resulted in me believing that I needed to make some changes in my own health regimen.

Well, all that to say that given you did not have problems with other brands of B, I suspect something is wrong with the new brand you are using. If you are using a synthetic brand, or something that is not up to standard maybe on the cellular level, this may be causing the "depression" reaction. Change brands.

You ask another question; why take the B complex and can you get what you need from a good diet. There are lots of books on that subject and the Vitamin supplement issue was one I first read about 40 years ago. Depleted soils, processed foods etc., convinced me that supplements are important for optimum health.

I read somewhere that some people genetically need another form of the vitamin 12 complex as they don't process it to the methyl form of vit b12 which the body needs. You may wish to look into that.

My spouse eats a lot of nutritional yeast to flavor his food in place of salt and many families eat certain meals more than others. It is always possible to get too much of something if you are unaware, it is already in your diet. Like fortified cereals and breads. I take some B's daily and others as I feel led. Sometimes I skip everything and then slowly add stuff back into my diet. P5P is a safer form of higher dose use of B-6. B complex is lacking many things, high in some and low in others, read the label. If your gut is healthy, it will make b vitamins and if it is really bad it might not absorb your b supplements. Too much B will increase your appetite.
